Seek assistance of a certified rigger if you feel you cannot perform the following steps cor-rectly. This rigger or yourself must follow precisely the following steps in order to perform acorrect and safe assembly of your canopy on your harness/container.

Your range canopy is delivered with lines ready to be mounted on your soft links, and eachgroup of lines and both steering lines are installed on a dedicated plastic sheet. Soft links aredelivered separately. To avoid any misrouting, you must route each soft lik through eachcorresponding line before disconnecting the lines from the plastic sheet.

At this stage mount the soft links on your risers making sure to respect each left and right frontgroups and left and right rear groups. As soon as assembly is done, check if lines routing is cor-rect and if each line is at the right place inside each group. Do not forget to have each steer-ing line going through the right slider grommet. Left rear grommet for the left steering line andright rear grommet for the right steering line.

Assembly of steering lines to your toggles is up to your harness/container brand. So, report toyour owner’s guide for such instructions.

To proceed correctly, report to your harness/container owner’s guide and follow the followingsteps.You will find three marks on the lower steering lines (under the brake loop): - Higher mark is a short setting and canopy will react quickly (short).- Medium mark is a neutral setting and give a bit of delay before reacting (neutral). - Lower mark is a long setting and give a delay before reacting (long).Make sure to choose the right setting according to your needs andtechnical level of flight. We are recommanding you to start with the neutral setting for the firstjumps and to adjust later a more appropriate toggle setting, once you have understood how thecanopy is flying. To do so, start making a knot. Once you have set the right length, proceed to afinger trapping secured by a bartack seam.


Canopy assembly on risers

You must proceed to the mounting of the soft links on the risers by following the stepsdescribed on the pictures below. No other brand of soft link is allowed for use with Basik AirConcept canopies.Basik Air Concept used two types of soft links:For reserve and Tandem canopies they are identified by a “R” on the tag sewn on the links.For main canopies they are identified by a “P” on the tag sewn on the links.To assemble the risers on you harness/container, please report to you harness/container owner‘s guide.


Packing

As soon as you start picking up your canopy after landing, you should already start organizing thepacking. It is important to avoid to drag lines and canopy, main bag and briddle and pilot chuteon the ground.To do so, you must: be facing the canopy, walk toward it and pick up the lines like a lasso untilhaving the slider against the canopy.

Before starting packing, it is important to check if lines are not misrouting or twisted. To checkthis, you must have your risers and steering lines between your fingers and your hands holdingsline groups as shown on the picture below. In case of crossing or twist, you must route the linesproperly before going further. If you feel unable to do it, seek assistance of a qualified person.

Your slider must look like shown on the below left picture. To set it back to is normalposition, you must insert the drawstring stops into the channels. This is accomplished byextending the drawstring slightly farther, and tucking the drawstring stop into the fabricchannel. Grasp and pull the fabric channel from opposite ends, extending the slider to its fulllength and reseating the pull tab in the channel.


Now put down the harness/container on the floor by taking care of:- having the container-side up,- having both main risers symetrical.

At this point, go toward the canopy and free it from main pilote chute, bag and briddle.Look at the trailing edge and go to the steering lines. Take each of them between your fingersand untwist them by rolling the line between your fingers down to the toggles.

Set half brakes on by following your harness/container owner’s guide.For an Advance container type “In” and/or “Out”: please follow instructions into your owner’sguide too. Pictures below are showing all these Advance types steps.


As soon as brakes are on, setting of your harness/containershould look like the picture below.

Use your hands to split each line group and steering lines as shown on the picture below. Then,go toward the canopy by pushing the slider up at the same time. Move all lines groups and steer-ing lines up on one of your shoulder, and start to pull each cell out (7 or 9).

Take all cells in one hand and flake the entire nose. Start by one side and clean each lines groupA-B-C- by stowing material.

Do the same for the other side and set the slider in a cross position right in the middle.


When finished, your canopy should look like on the left picture.

Clear stabilizers when moving toward the trailing edge. Make sure none of the lines are wrappedaround a slider stop on a stabilizer.Fold all material between each steering line. All steering lines, related material and D lines groupmust stay set in the tail center.

Reach down and pick up the very middle point of the trailing edge (where warning panel is sewn).Raise the tail a couple of inches above the slider and hold it in place. Take both tail pieces (leftand right) in one hand, and roll them together in to the middle (no more than 8 turns) by keep-ing tension down. Start these rolls by the lower parts of the tail. Do not roll them too much, thiswill not help slow down the opening but will bring back the steering lines toward the nose of thecanopy. By doing so, you can create a line over configuration and have your canopy damaged.

At this point, your canopy must look like a roll. Swing it out slightly so that the lines stay tautand gently lay it on the floor. Beware to maintain tension on lines.


Have your main bag ready. Kill-line users must untwist the line and the briddle connected to thebag; these 2 items must be parallel.

Pull the kill-line briddle to reduce the lack of the inner line into the bag.

Lay on the canopy, taking care not to slack the lines and not to let the slidermoove out of the rolled canopy.

Make a first fold of the same depth as your main bag and maintain the canopy rolled shape withyour knees.


S-fold over the remaining of the canopy, making sure to keep it tight.

Slide the main bag under the folded canopy and insert each corner of the folded canopy into it.Make sure that the bag is symmetrically filled, then lock the bag with the first two line bands.Refer to your harness/container owner’s guide to verify the main bag closing sequence order.

Finish the lines stowage by keeping tension on them. Length of lines after the band must notexceed 5 cm. Check that lines are not crossing each other.Kill-line users must, at this point, verify that the inner line is pulled until the colored line can beseen in the bridle window.At this stage, refer to your harness/container owner’s guide for further packing and assemblyinstructions.


Collapsible Slider Post-deployment Procedure

After deploying pour parachute, check the canopy and surrounding airspace. Locate the 2 pulltabs at the rear of the slider. Grasp both tabs and pull down and back with a quick movement to the drawstring’s full length.This will allow the drawstrings stops to lock the slider in the collapsed position. Release the tabs and fly normally. The slider will remain collapsed.This procedure can be done before or after removing the half brakes, up to your habit.You can put the slider down through your risers if you like. We do not recommand to put theslider behind your head because it could become a problem should you perform a breakawaybefore landing.

Explanations on Hard Openings

Hard openings may come from different factors:- Packing- Slider setting- Bagging the canopy- Line stow and bands quality- Main pilot chute- Opening body position- Deployment speed

1 - PackingFollow the canopy manufacturer's packing guidelines. An asymmetrical packing with linescrossing material and/or lines not taut are a hard opening cause.

2 - Slider settingThe exact position of the slider inside the pack job greatly influences the opening speed of thecanopy. It is important that the slider be all the way up the lines, with each and every slidergrommets seated against the slider stops. There should be no twists in the lines above the slider, since they would tend to push the slider down the lines prematurely.

3 - Bagging the canopyThe correct canopy folding and slider position must be maintained while putting the canopy inthe bag. If it goes into the bag disorganized, it will likely come out disorganized and open hard.You must take time to learn how to put clearly the canopy into the bag. If it is asymmetrical, themain bag could goe up turning and create line twists as well.

4 - Line stow and bands qualityLines must be released one stow at a time. When the pilot chute pulls the bag it rapidlydecelerates the bag. If the lines are not stowed securely to the bag they can all slip out at once.This is what we call “line dump”; this can lead to a very dangerous out of sequence opening. Ifthe canopy is released from the bag and start opening before it has reached line stretch, open-ing will be hard. Canopy will start filling with air almost instantly while canopy and lines go every-where.This scenario can damage canopy, lines, risers and really cause serious injuries. So checkfor quality band retainers and switch them often.


5 - Main pilot chuteThe pilot chute has big influence on canopy deployment. The size, type of fabric, length of bri-dle, apex length, mesch size, and aerodynamic shape all afect the deployment of the parachute.We are not going to speak about all of these aspects, parachute manufacturers know what kindof pilot chute must be used. You just have to check the following:Pilot chute must be replaced every 250 jumps if made of F-111 fabric.Pilot chute must be replaced every 450 jumps if made of zero-porosity fabric.Pilot chutes made of ZOP fabric tend to provoque bad openings because of their slipering capa-bility when released. Inner kill-line retract jump after jump because of the heat friction whenactivating. Jump after jump the pilot chute will collapse because of this retraction and the pilotechute will loose efficiency. This line must be replaced every 250 jumps. 6 - Opening body positionToo many think they are stable on opening just because they are in a belly bell position. Manyare not aware that they are moving in different directions because of a slight tilt. What’s more,when you are watching your pilot chute after releasing it, your shoulders are not parallelanymore. This pitch difference between both shoulders can be up to 40 cm; this difference isreported to your risers and your lines as well, leaving little chance for an on-heading opening. Itis also important to be relax into your harness during deployment to avoid any asymmetric open-ing. Last thing, any action on risers can create turns on opening.

7 - Deployment speedOur canopies are made to be used at a maximum velocity based on a belly bell position plus 15%.If you open at a higher speed, you might experience a severe hard opening.

We hope that these explanations will help you understand some of the reasons which may causehard and bad openings.

Maintenance and Repairs

Only an experienced and certified rigger can repair our canopies. Material and toolings used forsuch repairs must be the same as original material and toolings used for manufacturing. Heavyrepairs like replacing a load bearing cell must be done only in our factory unless an agreementhas been given to a repairing facility.
